To all whom it may concern: liquid circulation or liquid-circulating sys- Be it known that I, JOHN BROWN FRANCIS tem. This water passes ofi through a series HERRESHOFF, a citizen of the United States, of escape pipes or. The casting device reresiding in the borough of Brooklyn, county ceives water from an annular pipe through 5 of Kings, State of New York, have invented a connection 10, which annular pipe receives certain new and useful Improvements in water from a series of radiating pipes q,which Metal-Oasting Apparatus,of which the followradiate from an upright pipe 7', which is ing is a specification. stepped after the manner of a shaft in the My invention relates to an apparatus to be pipe or footstep d and is packed therein by to employed in casting, the said apparatus bea suitable gland s, so that the structure coning especially adapted to cast thin flat bodies, stituted by the pipe 1" and the footstep d conand is of particular use in casting anodes. stitutes a pivotal structure upon which the One form of apparatus embodying my inentire movable apparatus pivots. An annuvention is described herein, and the characlar trough t is provided, into which the es- :5 teristic features of the invention are pointed cape-pipes n empty. A mold 'u, is seated in out in the claims at the end of this specificaeach casting device and is cooled by the wation, it being understood that while I have ter circulation. It will be observed that these shown and described but one form of my apmolds are herein shown as anode-molds and paratus other forms may be employed withare employed for the purpose of casting a flat 7o 20 out departing from the spirit of my inven plate or anode. The leveling of the mold is tion. effected by leveling the casting device by In the accompanying drawings I have means of leveling'screws '0.

The means whereby the cooling liqisuid circulates around the molds constitutesa 1. The combination of a series of molds each having a liquid-circulating system, with means for causing the said molds to travel in aclosed path, a stationary platform supported within the path of travel of the molds, a water-supply pipe forming the pivot of the system of molds, located beneath the platform and in liquid-conducting communication with the liquid-circulating systems of the molds, a furnace or other source of moltenmetal supply and a trolley-supported ladle arranged in operative relation with the furnace and the moving molds.

2. The combination of a series of molds, each provided with a liquid-circulating system and with means for supporting the same and causing them to travel in a circular path, a platform located within the circular path of the molds, a water-circulation system, a central supply-pipe therefor, the said central supply-pipe located below the platform constituting the pivot of the rotating series of molds and in liquid-conducting communication withihe liquid-conductingsystems of the molds.

3. In a casting device, the combination of a mold and a water-bath therefor, which consists of an inner and an outer casing, means for supplying water to the inner casing, the said inner casing having liquid-outlet apertures at or near the top thereof, and an outlet-pipe for the outer casing.

4. In a casting apparatus, the combination of an annular framework, a series of casting devices carried thereby and leveling devices for leveling the casting devices independently of the framework.

5. In a casting apparatus, the combination having liquid-circulating systems, means for rotating the framework, a central supplypipe for supplying a cooling liquid and constituting the pivot of the apparatus, the said water-supply pipe being in liquid-conducting communication with the mold-liquid circulating systems, a stationary platform located within the annular framework above the central supply-pipe and means for pouring the molten metal.
